Electron package

I love this project, it becomes so easy to develop beautiful GUI for python apps and the abstraction is great. In my last project, I switched from the Chrome browser to Electron so I could customise the windows appearance and behaviour. It works almost flawlessly; I can't package the app anymore.

I also tried to use a local Electron release and use relative paths

# eel.browsers.set_path('electron', 'node_modules/electron/dist/Electron.app/Contents/MacOS/electron')
eel.browsers.set_path('electron', 'Electron.app/Contents/MacOS/electron')

And tried adding the Electron app to the pyinstaller command:

python3 -m eel main.py web --noconfirm --noconsole --onefile \
--add-data /AbsolutePathTo/Electron.app:Electron.app \
--add-data electron_main.js:Electron.app/Contents/Resources/app

My different tries result in different errors such as FileNotFoundError: [Errno 2] No such file or directory: 'Electron.app/Contents/MacOS/electron': 'Electron.app/Contents/MacOS/electron' () or Cannot find module '/Users/xyz'. Require stack: /usr/local/lib/node_modules/electron/dist/Electron.app/Contents/Resources/default_app.asar/main.js

I started from the Eelectron example with macOS 10.15 / python 3.7.7 / pyinstaller 3.6

Has anyone achieved this and is willing to help me?
